Details:

The SR-RAIL M-LOK series from 2A Armament is a universal rail that marries beautifully with most forged and billet receivers as well as 2A’s own BALIOS receiver sets. This rail is designed to meld perfectly with the top rail upper receiver that is standard to most AR-15 type rifles. When the SR-RAIL M-LOK is properly mounted using the included aluminum barrel nut and secured with 2A’s exclusive 45-degree tension screw system the result is a lockup that is second to none. When properly fitted the rail to receiver attachment is almost seamless and it free-floats perfectly.

2A Armament offers the SR-RAIL M-LOK in 7, 10, 12 and 15-inch sizes to accommodate your preferred barrel and gas system length. The inside diameter of this SR rail is and unobtrusive 1.3 inches. Each rail is manufactured from Certified 6061 extrusion material and is anodized in black for a Mil-Spec hardcoat finish. The result is an economical rail that is both good looking and tough enough to hold up under heavy use.

In addition to standard Picatinny recoil grooves, this SR rail offers the option to mount additional items with the cutting edge M-LOK slot system. Using M-LOK mounts you can quickly and securely mount a variety of accessories to the handguard without having to access the back side of the mounting surface.

Each 2A SR-Rail comes complete with an aluminum barrel nut and hardware. It’s ready to install on arrival without purchasing additional items. Just follow the included instructions and you'll be ready to experience the difference quality American made products make in your AR build.

First Rate Product

2A makes some of the best handguards in the business. SR rails are slightly heavier than the BL rails but the SR looks seamless with my upper. The machine work is first rate, finish is impeccable. I love how the handguard fastens to the barrel nut, very ingenious and simple to install. Barrel nut is best to install with a crow's foot. Wing tactical is awesome, fastest shipping in the business. Thank you!
